Juniper bests Cisco, others for NYSE upgrade

Low latency 10G Ethernet network planned to connect data centers

Cisco was but one vendor to lose out on a network upgrade at the New York Stock Exchange. NYSE chose Juniper to outfit it with a low latency 10G Ethernet network to connect data centers in New Jersey and London.

NYSE will deploy 20 to 40 Juniper EX 8216 switches in its core and "a couple hundred" EX 2500s in the access layer of the network, NYSE officials said. In addition to the switches themselves, latency gains will be derived by eliminating a layer of switching and routing in the NYSE network, officials said. The exchange is flattening its network into a 2-tier architecture from a three-tier construct, officials said.

NYSE has no definitive timeline for upgrading the network to 40/100G Ethernet but will move quickly when standards and products are firm. The network will achieve latency levels in the low 10s of microseconds over the next several years, NYSE officials said.

NYSE will be an early adopter of Juniper's next-generation data center fabric, currently being developed under the Project Stratus code name, Juniper officials said. That effort is expected to include a significant 40/100G Ethernet component.

The exchange evaluated "all major and some minor" vendors for its 10G/low latency project, officials said. They found Juniper to have the more favorable products and roadmap, they said.
